ADF-2 Gerber and Dril Data ReadMe File ---------------------------------------- Original Rev. 8-NOV-2004 Current Rev. 22-NOV-2004 This file contains a description of the Gerber Data and the Drill Data for the ADF-2 circuit board. --> The Gerber and Drill data that was posted on the <-- --> web on 22-NOV-2004 is released for manufacturing. <-- Gerber Data: ------------ There are 18 Gerber files in this directory. There functions are: Filename File Contents Stackup Layer ------------ ------------------------------ -------------------- adf_2_art_1 Component Side Traces 1 Stackup Layer 1 adf_2_art_2 Internal Traces 2 & VEE Plane Stackup Layer 2 adf_2_art_3 Ground Plane Stackup Layer 3 & 10 adf_2_art_4 VCC Planes Stackup Layer 4 adf_2_art_5 Internal Traces 3 Stackup Layer 5 adf_2_art_6 Internal Traces 4 Stackup Layer 6 adf_2_art_7 Internal Traces 5 Stackup Layer 7 adf_2_art_8 Internal Traces 6 Stackup Layer 8 adf_2_art_9 VDD Planes Stackup Layer 9 adf_2_art_11 Internal Traces 7 Stackup Layer 11 adf_2_art_12 Solder Side Traces 8 Stackup Layer 12 adf_2_art_13 Component Side Silk Screen adf_2_art_14 Solder Side Silk Screen adf_2_art_15 Component Side Solder Mask adf_2_art_16 Solder Side Solder Mask adf_2_art_17 Component Side Paste Mask adf_2_art_18 Solder Side Paste Mask Note: There is no File Number 10. The data for the Layer 10 Ground Plane is the same as for the Layer 3 Ground Plane. ARTWORK FORMAT ---------------------------------------------------- Photoplotter coordinate mode: Absolute Photoplotter does not support circular interpolation Arcs and circles are interpolated by 8 segments Photoplotter supports Gerber G code Photoplotter units: MILLIMETER Scale is 1.000 Data format 3.2 Leading zeros are present Trailing zeros are present Photoplotter modal coordinate is off Photoplotter modal shutter open (D01) is off Record length of the artwork output file is 80 Manual offset specified has shifted artwork data(x,y) : 0.00 , 0.00 Photoplotter command block end char is '*' Photoplotter machine stop code is 'M02' Thermal Ties ------------------- All thermal ties should run at 45 degrees to the vertical and horizontal. Trace Widths and Pad Sizes ------------------------------ The trace widths and pad sizes indicated in the Gerber data are the desired finished sizes of these objects. Drill Data: ----------- DRILL TABLE ----------------------------------------------- Drill Finished Position Diameter mm Plated Count -------- ----------- ------ ---------- 1 0.30 yes 3533 2 0.60 yes 310 3 1.00 yes 320 4 1.00 no 4 5 1.09 no 12 6 2.70 no 9 Note: The 0.30 mm diameter holes are for electrical connectivity only. No component lead goes into these holes. The finished size of the 0.30 mm diameter holes may be adjusted by the manufacturer for best fit with the associated via pads. These 0.30 mm holes may close in. DRILL FORMAT ------------------------------------------ Drill machine coordinate mode is: ABSOLUTE Drill machine units: MILLIMETER Scale is 1.000 Data format is 3.2 Leading zeros are PRESENT Trailing zeros are PRESENT Drill machine modal coordinate is OFF Drill machine origin (x, y) at (0.0, 0.0) Drill machine command block end char is '' Drill machine stop code is 'M30'
